Electric-generator monitoring and diagnostics
Abstract
Turbine generator availability is improved by developing on line monitoring instrumentation capable of early detection of developing malfunctions. The development work on an on line RF monitor and a fiber optic temperature sensor are reported. The RF monitor detects internal generator arcing and alerts the operator if the arcing level becomes destructively high. The fiber optic temperature sensor detects hot spots in generator stator windings, a high voltage and high electromagnetic flux environment.
